FIG. 1 is a front plan view of an marker showing our new design;

FIG. 2 is a left side plan view of the marker of FIG. 1;

FIG. 4 is a rear plan view thereof;

FIG. 5 is a bottom plan view thereof; and,

FIG. 6 is a right side plan view thereof.

The broken lines in the drawings show environmental structure and form no part of the claimed design. The diagonal lines (or shading lines) are intended to show that the respective portion(s) of the marker are transparent, whereas the claimed portion(s) of the marker that do not include such lines are opaque. 

I claim, the ornamental design for an image marker, as shown and described.
